AN TISKÍD‘ ATTACHMENT
Eugène Granger, St.
Application February 16, 1938, Serial No. 190,819
(Cl. 152-228)
3 Claims.
The present invention relates to improvements
in anti-skid attachments for vehicle wheels.
An important object of the invention is the
provision of an anti-skid attachment which is
5 relatively simple and durable in construction.
ì
Another object of the invention is the provision
of an anti-skid attachment which is designed to
members C by means of tightly fitted rivets l5 or
furnish eñective means to eliminate or reduce side
ber L, are disposed to assume spaced relation and
are hingedly connected by means of a relatively
short angle bar i6 providing a connecting bracket
having one ñange arranged parallel with one
flange of each of the sections and attached there
to by loose rivets or' headed bolts il’. This is
adapted to provide a> flexible structure at the 15
slip or spinning of a wheel.

L each of which is composed of a pair of comple
mentary sections I4, in the form of rigid straight
>angle bars. The remotev ends of each comple
mentary pair of bar sections I4 are rigidly con
nected with the respective end forming cross
Another object of the invention is to provide
an anti-skid attachment of the aforesaid char
acter embodying hinged sections constructed to
articulate in operation.
-
-Another object of the invention is the provi
sion of an anti-skid attachment of the above
character which may be conveniently mounted
upon or removed from a vehicl-e wheel.
`
Other objects and advantages of the invention
will become apparent as the description pro
20 gresses.
In the accompanying'drawing forming a part
of this specification and in which like reference
characters are employed to designate correspond
other suitable fastening elements. The adjacent
ends of the sections it, of each longitudinal mem
centre of the longitudinally extending members
of the attachment.
This attachment is mounted on a-vehicle wheel
by disposing the cross members C transversely of
the tread portion of the wheel, as shown at Fig
ure 3, the flexible connection of the sections and
the angular formation enabling these members to
substantially conform to the tread and adjacentv
side wall curvature of the wheel or the tire there
on. vThe hooks il formed on the outer ends of
the cross members are disposed to engage links
of annular fastening chains i8 arranged at op
posite sides of the wheel. The longitudinal mem

form of the attachment,

Referring >to Figures 1 to 4 inclusive, wherein isI
40 illustrated a‘ preferred embodiment of the inven
tion, “C” generally designates each of a pair of
cross members of the attachment device. Each
of the said cross members is composed of a pair
of complementary narrow bars It bent longitudi
45 nally intermediate their ends, as shown to advan
tage at Figures 1 and 2, and having the outer end
portions bent inward to form U-shaped attaching
hooks ll.
The inner adjacent ends of the com- '
plementary sections lil are bent over outwardly to
50 engage opposite side'portions of a rectangular
` Figures 5 to 7 inclusive, embodies cross members .
D composed of a pair of angularly bent bars 2i!
having bent over hook forming end portions 2l
and similar to the formation of the sections l!)
of the preferred form. These cross bars 2|) differ
from those- in the preferred form in that they
are formed with la right angular flange 22 dis
posed to project from the wheel and having a
diminishing taper toward the outer end of each
bar, as shown to advantage at Figure 7. The in
ner adjacent ends of the sections 2li are connected
by an angle bracket 23 connected by loose pivots
or bolts 2d with the sections.
A pair of relatively narrow parallel longitudi
nal members M extend between and connect with
the cross members D and embody a pair of angle
shaped connecting or hing-e link I2, flexibly join- ~ bars 25 having their adjacent ends connected
through the medium of an angle bracket 26 and
ing the sections I0 in aligned relation.
Attached to and extending between the cross
members C, at right angles thereto, are a pair of
55 parallel relatively narrow longitudinal members
rivets 21.
In this form of the device, the remote ends of
the longitudinal members M are flexibly connect 55

ed with the transverse members D this being
eiîected, in the present instance, by means of
U-shaped loops or stap-les 28 having the end p0r
tions extended through apertures in the flanges
22 of the cross bars and bent over to fastening
ture of the tread portion of a Wheel, means
on said transverse members for connecting the
same with fastening chains, a pair of longitudi
nal members connected With and arranged at
right angles to the cross members, each of the
said longitudinal members including a pair of Ul
position, as clearly shown at Figure 5, and hav
ing the intermediate looped portion extended, rigid angle bars, and means hingedly connect
through an aperture in the remote end portion ing the adjacent ends of the angle bars to» form
of each of the longitudinal bars 25.
10
This modification of the anti-skid device is
mounted on a Wheel in a manner similar to- the
mounting of the preferred form, but provides
greater ñexibility and additional gripping flange
structure.
15
The attachment provides an anti-skid device
which, although relatively simple and inexpen
sive in construction, embodies an attachment
which is very durable and, due to the arrange
ment of the component bars and the projecting
20 flanges thereof, is highly eñîcient in affording
traction and for reducing side slip» as Well as
spinning of the Wheel to which it is attached.
It is to be understood that the forms of my
invention herein shown and described are to be
25 taken as preferred examples of the same, and
that various changes as to the shape, size and
arrangement of parts may be resorted to With
out departing from the spirit of the invention or
the scope of the subjoined claims.

Having thus described my invention, I claimz--l. An anti-skid attachment for vehicle wheels
comprising a pair of cross members, each of the
said cross members including a pair of rigid bars
having their adjacent ends hingedly connected
35 and shaped to conform to the transverse curva
a flexible joint intermediate the ends of the lon
gitudinal members.
2. An anti-skid attachment for vehicle Wheels
comprising a pair of end cross members, each
of the said cross members including a pair of
rigid bar sections having their adjacent ends
hingedly connected, a pair of longitudinal mem
bers rigidly connected with and extending be
tween the cross members, each of the said longi
tudinal members including a pair of rigid angle
bars, and means hingedly connecting the adja
cent ends of the angle bars to form a flexible
joint intermediate the ends of the longitudinal
members.
3. _An anti-skid attachment for vehicle wheels
comprising a pair of cross members, each of the
said cross members including a pair of rigid bars
bent in angular form, a link hingedly connect
ing the adjacent ends »of the said bars, a pair of
longitudinal members having the end portions
hingedly connected with the cross members. each
of the said longitudinal members including a pair
30
of angle bars, and a bracket connected by pivot
members with the adjacent end portions of the
angle bars `to form a flexible joint intermediate
the remote ends of the said members.
